Abstract: An absorbent sheet manufacturing apparatus is provided with a cylinder part (21) having a plurality of through-holes (212) arranged in a circumferential direction. The cylinder part (21) is rotated, and therefore particles of high-absorbent resin are sequentially filled into the through-holes (212) from a particle storage space (217) in the cylinder part (21). In a particle supply region (210) of a lower portion of the cylinder part (21), the inner side surface (215) of the cylinder part (21) is covered with an isolation part (25) so that each through-hole (212) filled with particles is isolated from the particle storage space (217). And in this state, particles are ejected from the through-hole (212). As above, only particles filled in each through-hole (212) are ejected, and therefore a desired amount of particles can be easily supplied from the through-hole (212).
